Atlantic Sets Record for Latest First Hurricane as Season Remains Unusually Quiet

A powerful El Niño is producing record-strength upper-level winds that have suppressed storm formation across the Atlantic.

Overview

  • The season reached Sept. 12 with no hurricanes, the longest wait for a first Atlantic hurricane in the satellite-era at roughly 103 days.
  • Forecasters and researchers say a very strong El Niño has driven record-high vertical wind shear over the basin, which has repeatedly torn apart developing storms.
  • Measured activity is extremely low with only five short-lived named storms so far and accumulated cyclone energy at the lowest value through this date since 1950.
  • The National Hurricane Center expects no tropical development in the coming week, but some private forecasters still see a modest late-season uptick and the Gulf of Mexico remains a known area where storms could form.
  • El Niño has shifted activity into the eastern and central Pacific, producing well-above-normal hurricane activity and raising concern that leftover warm Atlantic waters could increase the odds of a busier season next year.
